Salient Characteristics SpecificationTitle: Galvanized Steel Quick-Disconnect Ductwork and Components for Air-Conditioning SystemSubject: Supply of modular galvanized steel quick-disconnect ductwork, fittings, dampers, and support hangers.Basis of Design: The part numbers below are for reference and configuration cross-reference. Products offered may be from another acceptable manufacturer, provided they meet or exceed all salient characteristics and are fully compatible with the complete ductwork system.1. Scope and PurposeThis requirement is for the supply and delivery only of galvanized steel, modular quick-disconnect ductwork and associated fittings for an air-conditioning system. The supplied components shall form a mutually compatible duct system consisting of straight duct sections, reducers, wye connectors, elbows, airflow dampers, and saddle hangers.Installation, field fabrication, field welding, and connection to existing equipment are not included unless specifically added elsewhere in the solicitation.2. General Salient Characteristics. All offered items shall meet the following minimum requirements: Material: Items 1 through 26 shall be galvanized steel only. No stainless steel, aluminum, plastic, or uncoated carbon-steel substitutes shall be accepted.System Compatibility: All duct, fittings, dampers, and hangers shall be compatible with the specified quick-disconnect duct system. Components of the same nominal duct diameter shall connect directly without adapters, field welding, rivets, sheet-metal screws, or permanent field modification.Quick-Disconnect Connection: Straight duct sections, reducers, wye connectors, elbows, tees, and dampers shall use a quick-disconnect connection configuration compatible with the remaining supplied components. Connection features shall permit assembly and disassembly of the duct system without damage to the duct or fittings.Nominal Dimensions: Duct diameters and fitting dimensions listed in the schedule are nominal inside diameters unless the manufacturer���s standard quick-disconnect system identifies dimensions differently. Reducers shall transition between the listed inlet and outlet diameters. Fittings shall be sized to directly mate with the corresponding duct diameter.Gauge Requirements: Straight duct sections and dampers shall be 20-gauge galvanized steel where identified in the schedule. Reducers, elbows, wye connectors, tees, and 90-degree fittings shall be 18-gauge galvanized steel where identified in the schedule. Saddle hangers shall be 14-gauge galvanized steel where identified in the schedule.Quality and Condition: Products shall be new, free of corrosion, dents, sharp edges, cracks, deformation, damaged coating, or manufacturing defects that would prevent proper assembly or service. Duct sections shall be round, and fittings shall retain their intended shape to allow proper connection. Components shall be packaged and shipped to prevent damage or distortion in transit.Equal Products: …
